Multi-criterion decision making for disassembly line balancing problem

Abstract

A disassembly line balancing problem (DLBP) aims at streamlining the disassembly activities such that the total disassembly time consumed at each workstation is approximately the same and approaching the cycle time. The assignment of disassembly operations to workstations in a disassembly line should ensure the recovery of valuable components and reduce undesirable impact on the environment as much as possible. This paper first studies a multi-criterion decision making (MCDM) for the DLBP by means of grey relational analysis (GRA) and Choquet fuzzy integral. Based on the ranking of MCDM, we develop a fast ranking heuristic approach to determine the optimum/near-optimum disassembly sequences. The proposed approach is illustrated with a real-world example and the results show its efficacy in solving the DLBP.
